• Regulation:
a) Static : Steady state regulation is ±0.6% as controlled within the rectifier for any and all
combinations of load from no load to full load, input voltage, and input frequency at a
constant ambient temperature. The associated system Controller may provide increased
regulation.
b) Dynamic : Response time≤200us and overshot≤5% for load changes at 50%-25%-50%
and 50%-75%-50% at rated output voltage and current, meets YD/T731-2008.
For any step load change within the range of 10% to 90% of full load within 1 milliseconds,
per Telcordia GR-947-CORE, the maximum voltage transient will not exceed 5% of the initial
steady state voltage within 250±10 microseconds. Recovery to within 1% of the initial
steady state voltage does not exceed 4 milliseconds.
• Filtering:
a) Voice Band Noise: Complies with YD/T-731-2008.
1. Peak-peak voltage is ≤200mV at 0-20MHZ and normal output voltage. (YD/T-731-2008)
2. Psophometric noise is ≤ 2 mV typical at 220Vac input,53.5 Vdc output and 30% to 90% of
rated load for more than one rectifier.
b) Wide Band Noise: Complies with YD/T-731-2008.
1. Wideband noise emission is < 20 mV between 25HZ-20kHz according to ETS 300132-2 .
AC Input Ratings
• Voltage: Nominal 208/220/230/240 volts AC, single phase, 3-wire, 50/60 Hz, with an
operating range of 200 to 250 volts. Acceptable input frequency range is 45 to 65 Hz.
Permitted Variation: 85 to 305 VAC.
Harmonic Content (THD): Meets EN61000-3-2. :
≤5% .from 50% to 100% of rated output current at 220Vac,50Hz, 53.5Vdc and 25°C;
≤15% for 20% rated output current at 220Vac,50Hz, 53.5Vdc and 25°C.
• Inrush Current: Peak does not exceed 1.5 times of the peak value of the maximum steady-
state input current at full load,220 Vac input voltage, and for any duration of AC input
interrupts. Under the above conditions, standard AC distribution circuit breakers will not
trip.
• Typical Input Data: 50 Hz input.
a) Refer to Table 1.
b) Maximum Input Current: Refer to Table 2.
